zero lessons learned from the first game. non-existent level design, non-existent encounter design, non-existent gunplay. even the bosses are so easily abused with slow-mo mechanic that you can count them as non-existant too. also being a roguelite is a complete false advertisement, there is no permadeath and no procedural generation. the only reason the score is not lower is because GZDoom gives a foundation that makes the game at least not awful to play.
